INSULATOR FOR HEATlNG-P|PES..

. SPECIFICATION forming part of Letters Patent No. 441,644, dated December 2, 1890.

Application filed June 3, 1890. Serial No. 354,180. (No model.)

To all whom it may concern:

Be it known that I, GEORGE W. CONDERMAN, a citizen of theUnited States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Insulators for Heat-Pipes; and I do hereby declare the following to be a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

In steam-heating systems it has been found where pipes pass through the floors of a house that the heat of the pipe will sometimes set fire to the adjacent wood, or else render the same so dry and inflammable as to be easily ignited.

It is the object of my present invention to provide and produce a device for insulating these steam-pipes, whereby no heat can be transmitted to the wood-work from the pipe, and wherebyavery artistic finish is produced where the pipe enters or leaves the floor or ceiling.

The principal novelties in my invention consist of a double metallic sheath adapted to fit between the ceiling and the floor, an ornamental plate or rosette at the top and bottom of said sheath, and a filling of asbestus or other non conducting material placed within the sheath, all as will more fully be hereinafter described and claimed.

For a better comprehension of my invention attention is invited to the accompanying drawing, forming a part of this specification, and in which the figure illustrates a sectional view of my invention.

A A represent the ordinary joist or beam, to the top of which are nailed the floorboards B B.

C 0 represent the laths secured to the under side of these joist in the usual Way, and D is the ordinary plastering. This is the way floors are usually constructed in this country; but this is secondary to my invention, and it should be understood that myimproved steampipe insulator may be used with any construction of floors.

E represents the steam-pipe of my improved steam-heating system, which passes up within a suitable opening out within the flooring.

This opening is made somewhat larger than the steam-pipe, so as to permit of the insertion of my improved insulator.

Ct represents a metallic tube around the steam-pipe and extending some distance up from the lower line of the flooring. The preferable material of this tube is tin, since this metal is cheap and may be easily worked; but it should be understood that brass .or iron or any other suitable metal may be used in place of tin.

1) represents another tube or sheath fitting tightly around the opening in the flooring. The upper end of this tube 12 is flanged over on floor at 0, so that the tube or sheath will retain its position within the opening. This sheath or opening is also preferably made of tin,but, like the tube a, may be made of any other metal; but it will also be evident that these tubes may be made of heavy paper or fiber. At the lower end of the tube a and b is soldered or otherwise secured an ornamental circular plate or rosette e, which is preferably made of brass or other bright material. This ornamental plate may be artistically and effectively made of some nickelplated metal. In order that the flange c at the top of the sheath 1) may be effectively concealed, a separate ornamental plate e is used, which is placed over the steam-pipe and allowed to rest in position over the upperfiange 0.

Before the plate or rosette e is placed in position the'space between the sheath 1) and the tube or sheath a and the steam-pipe is filled in with asbestus or some other non-conducting material. This asbestus may be in any well-known commercial form, either as wool or sheets. The ornamentations on the plates d and e may be of suitable kind; or instead these plates may be perfectly plain. It will be seen that these plates not only form an artistic finish to the ceiling and floor, but that the lower plate d acts as a bottom for the asbestus to rest on, and that the plate 6 acts as a cover to exclude any dust or inflammable material. Then it is desired to remove the device or asbestus, all that is necessary is to raise the upper plate e, loosen the flange from the floor, and force the asbestus packing, the tubes at and b, and the plate d down from above. In some cases, as with a lower floor having a cel larbeneath, there is no necessity of making use of the two ornamental plates (1 and e. In such ICO a case the tubes at and b are inserted from above, so that the plate (l will constitute an ornamentation to the floor, and the asbestus packing is placed in the space formed between the tubes at and b.

When it is desired to use my improved insulator with pipes which have been already erected, they will be made in halves, which may then be easily inserted in position. \Vhen this latter course is resorted to, it might be advisable to secure the plates 6 and do in place by ornamental nails or screws or other ordinary fastenings, so that they will be held securely in position. It should also be understood that the device may be used with hotwater heaters and with hot-air heaters, or in any other cases where a very hot pipe passes through a floor.

As the insulation continues from the outside of floor above to the outside of ceilingbelow, it will be impossible for rats or mice to bring in contact with steam-pipe any material, combustible or otherwise, matches, 850.

Having now described my invention, what I claim as new therein, and desire to secure by Letters Patent, is as follows:

An improved heat-insulator for steam-pipes, consisting of a sleeve 1), fitted around the interior of the opening for the steam-pipe and flanged over at 0, so as to firmly retain its position, a sleeve a, fitting tightly around the steam-pipe and carrying an ornamental plate (1 at its lower end, which forms a support for the asbestus packing, which is placed within the space between the sleeve 1) and the sleeve a and steam-pipe, and an ornamental plate e above the sleeve 1) and surrounding the steampipe, so as to conceal the asbestuspacking and to exclude foreign substances, substantiall y as set forth.
